Let me carefully examine the image to identify what needs to be labeled.
First, I'll look at the top diagram with the earthquake cross-section. There are three labels pointing to specific parts:
- One points to "The point on the ground directly above the focus"
- One points to "A weak point in the tectonic plate where pressure within the crust is released"
- One points to "Where the earthquake begins. Also called the hypocentre."
Then there are three diagrams below showing different fault types:
- Left diagram: shows layers being pulled apart (tension), with a slanted break and one side dropping down.
- Right diagram: shows layers being pushed together (compression), with a slanted break and one side moving up over the other.
- Bottom diagram: shows layers sliding past each other horizontally.
I need to match these to the word list:
1. focus
2. fault
3. epicenter
4. normal fault
5. strike-slip fault
6. reverse fault
7. hanging wall
8. footwall
Let me analyze each part:
For the top diagram:
- "The point on the ground directly above the focus" = epicenter (item 3)
- "A weak point in the tectonic plate where pressure within the crust is released" = fault (item 2)
- "Where the earthquake begins. Also called the hypocentre" = focus (item 1)
For the left diagram (tension):
- This shows a normal fault, where the hanging wall moves down relative to the footwall
- The upper block that moves down is the hanging wall (item 7)
- The lower block that stays relatively still is the footwall (item 8)
- The type of fault is normal fault (item 4)
For the right diagram (compression):
- This shows a reverse fault, where the hanging wall moves up over the footwall
- The upper block that moves up is the hanging wall (item 7)
- The lower block is the footwall (item 8)
- The type of fault is reverse fault (item 6)
For the bottom diagram (horizontal movement):
- This shows strike-slip fault (item 5), where blocks slide past each other horizontally
Now I need to determine exactly which blanks correspond to which labels. Let me zoom in on the specific blank locations to be precise.
